1.1 These test methods cover procedures for the sampling and chemical analysis of inorganic alkaline detergents.
1.2 The procedures appear in the following order:
Sections Caustic Soda: Sampling 5 Total Alkalinity as Sodium Oxide (Na O) 6 to 8 Sodium Hydroxide (NaOH) 9 to 11 Carbonate as Sodium Carbonate (Na CO ) 12 Carbon Dioxide (CO ) by the Evolution Method 13 to 16 Soda Ash: Sampling 17 Matter Volatile at 150 to 155C 18 and 19 Total Alkalinity as Sodium Carbonate (Na CO ) 20 to 22 Sodium Bicarbonate (NaHCO ) 23 to 25 Sodium Bicarbonate (NaHCO ) by Potentiometric Titration 26 to 28 Matter Insoluble in Water 29 and 30 Apparent Density 31 and 32 Modified Soda (Sequicarbonate Type): Sampling 33 Total Alkalinity as Sodium Oxide (Na O) 34 to 36 Sodium Bicarbonate (NaHCO ) and Sodium Carbonate (Na CO ) 37 to 39 Matter Insoluble in Water 40 Sodium Bicarbonate: Sampling 41 Sodium Bicarbonate, Sodium Carbonate, and Free Moisture 42 to 45 Matter Insoluble in Water 46 Sodium Metasilicate, Sodium Sesquisilicate and Sodium Orthosilicate: Sampling 47 Total Alkalinity as Sodium Oxide (Na O) 48 to 50 Total Silica as SiO 51 to 53 Sodium Metasilicate (Na SiO 5H O) 54 Sodium Sesquisilicate (3Na O 2SiO 11H O) 55 Matter Insoluble in Water 56 and 57 Loss on Ignition of Sodium Sesquisilicate (3Na O 2SiO 11H O) 58 and 59 Sodium Orthosilicate (Na SiO ) 60 Trisodium Phosphate: Sampling 61 Trisodium Phosphate (Na PO ) Content and Phosphorus Pen- toxide (P O ) 62 to 64 Trisodium Phosphate Calculated as Na PO 12H O, Na PO H O, Na PO , and as P O 65 to 68 Total Alkalinity as Sodium Oxide (Na O) 69 to 71 Matter Insoluble in Water 72 and 73 Tetrasodium Pyrophosphate: Sampling 74 Tetrasodium Pyrophosphate (Na P O ) 75 to 79 Matter Insoluble in Water 80 and 81 Loss on Ignition 82 and 83 Borax: Sampling 84 Total Borate and Excess Alkalinity or Acidity 85 to 87 Matter Insoluble in Water 88 and 89 Sodium Triphosphate: Sampling 90 Tritratable Na O 91 to 94 To......
